This 48-page picture book chronicling the 2003 epic journey through the wild country straddling the Canada-Alaska border by newlywed Albertans Karsten Heuer and Leanne Allison documents the physical hardships, unexpected dangers and wondrous discoveries they encountered as they followed the 100,000 caribou over 1500 km on their annual trek to safe (but environmentally threatened) calving grounds by the Beaufort Sea.
